MOA adjustable jack plates

Has anyone here used adjustable jackplates for longer range shooting?

Specifically this one:. https://labalestramoderna.anotherweb.it/2018/08/23/ravin-jack-plate/



The Ravin jack plate is designed to be used on a crossbow with optic rail. Has something like 250 moa.



I personally have no experience with jackplates and most of the info online is meant for ELR shooting with high power cartridge rifles like the weatherby mag or swift220. For powder burners long distance shooting doesn't begin until your target is past 500-600yds. For an air rifle thats an extreme shot and for a crossbow as well.

So I'm wondering if this Ravin jackplate might be worth the price? Other optic rail jack plates meant for cartridge rifles cost $400-700


 
Thanks for all your input !

Only reason I was interested in the crossbow moa mount is that the adjustable rifle mounts cost upwards of $400 and sometimes over 600.

Ridiculous considering it's just the mount, no optics in it. It would make sense to get the best of you're trying to hit a pie plate a mile downrange but we're not doing that yet


 
Just printed this sidewheel and an ref indicator (blue) for ZB lite adjustable mount, still to make distance marking.
